. STOVE-OVEN.

SPECIFICATION forming part of Letters Patent No. 377,378, dated February '7, 1888.

Application filed April 2, 1885. Serial No. 161,013. (No model.)

To all whom it may concern:

Be it known that 1, Guns F. FILLEY, of St. Louis, Missouri, have made a new and useful Improvementin Stove Ovens, of which the following is a full, clear, and exact description.

January 11, 1881, I had Letters Patent of the United States granted me for an improvement in cooking stoves and ranges, in which the outer air at atmospheric temperatures is passed substantially directly into the oven of the stove or range, during its use to come in contact with the articles being cooked and afterward discharged from the oven.

In carrying out the improvement, and as then considered the most desirable means therefor, wire-gauze or finely-perforated metal was inserted in oven door or doors, the perforated portion extending substantially throughout the door.

The presentimprovement is a modification of the means used to carry out the same discovery.

It consists as follows: In place of filling the entire door with wire-gauze or finely-perforated metal, the gauze or perforated metal is used only in the lower portion of the door,and is omitted in the upper portion of the door, which upper portion is left 0penthat is, the air enters the oven through the wire-gauze or finely-perforated metal in the lower portion of the door and leaves it through the opening in the upper part of the door. The advantage of the modification is the quickening of the aircirculation. The air can more readily escape from the oven than when it has to pass through gauze, and hence it can more readily pass into the oven at the lower part of the door. The opening in the door also provides opportunity for viewing the interior of the oven during the cooking.

The annexed drawings, making part of this specification, exhibit the best mode ofcarrying out the improvement.

Figure l is a side elevation showing an ovendoor having the improvement. Fig. 2 is a vertical section on the line 2 2 of Fig. 1.

The sameletters of reference denote the same parts.

A represents the door of the stove-oven, which is of the usual construction.

B represents the surrounding plate of the stove, against which the door closes.

0 represents the wire-gauze or perforated metal, which is suitably attached to or seen red upon the lower part of the door-frame, and in combination therewith forms the door proper;

but this gauze or perforated metal does not entirely cover the frame. There is left at the upper part of the frame the opening D.

I am aware that heretofore in the otherwise solid oven-doors of cook-stoves perforations or openings have sometimes been made, and provided with registers, so that air could be admitted through said registers or the door made close, as might be desired; but in my invention there is no door proper at all,mcrcly a door-frame, which is provided with wiregauze, so as to be only partially covered.

A desirable grade of perforated metal to use is what is known to the trade as perforated tin, No. 1. Good results can also be obtained with No. 2, as in pending applications for Letters Patent filed, respectively, May 19, 1884, and August 27, 1885, and numbered, respectively, 132,101 and 175,516. Ihave shown other meanssuch as an opening beneath the stove-hearth filled with gauze, and an ovendoor consisting of an inner more finely perforated plate, in combination with an outer plate having coarser perforations. I desire in the present application to disclaim the construc tions referred to.

I claim A cook-stove oven door consisting of the frame A, having the wire-gauze or perforated metal G in its lower part, and open in its up per part at D, substantially as described.

GILES F. FILLEY.
